To characterize the atrial remodelling in mitral stenosis (MS). Twenty-four patients with severe MS undergoing commissurotomy and 24 controls were studied. Electrophysiological evaluation was performed 12 each group by positioning multi-electrode catheters both atria to determine following: effective refractory period (ERP) at 10 sites 600 450 ms; conduction time; delay crista terminalis (CT); vulnerability for fibrillation (AF). P-wave duration (PWD) determined on surface ECG. In remaining...
Sites of complex fractionated atrial electrograms (CFAE) and dominant frequency (DF) have been implicated in maintaining fibrillation (AF); however, their relationship is poorly understood.Twenty patients underwent biatrial high-density contact mapping (507 +/- 150 points/patient) during AF. CFAE were characterized using software to quantify electrogram complexity (CFE-mean). Spectral analysis determined the with greatest power sites high DF a gradient. CFE-mean was higher (less...
Introduction: Management of unstable intertrochanteric fractures poses challenges in terms obtaining stable fixation and good postoperative outcomes.There is a paucity clinical data comparing the commonly used Proximal Femoral Nail (PFN) Antirotation (PFNA) implants, especially relation to osteoporosis. Aim:To assess comparative performance PFN PFNA setting Materials Methods:Patients presenting with (AO 31.A2 31.A3) were included treated either or PFNA.Preoperative radiographs normal side...
Sites of complex fractionated atrial electrograms (CFAEs) and highest dominant frequency (DF) have been proposed as critical regions maintaining fibrillation (AF). This study aimed to determine the minimum electrogram recording duration that accurately characterizes CFAE or DF sites for ablation without unduly lengthening procedure.Fourteen patients with AF undergoing catheter had high-density (498 +/- 174 points) biatrial mapping performed during before ablation. At each point, 8-second...
Introduction Annually, millions of adults suffer hip fractures. The mortality rate post a fracture is 7%–10% at 30 days and 10%–20% 90 days. Observational data suggest that early surgery can improve these outcomes in patients. We designed clinical trial—HIP Accelerated surgical TreaTment And Care tracK (HIP ATTACK) to determine the effect accelerated compared with standard care on 90-day risk all-cause major perioperative complications. Methods analysis HIP ATTACK multicentre, international,...
The area of the functional sinus node complex exceeds that anatomical node; however, reasons for this discrepancy are unknown. We aimed to characterize in health and disease with high-density simultaneous mapping.Sinus activity was characterized 15 reference patients after ablation supraventricular tachycardia. A further 16 were studied following chronic atrial flutter determine effects remodeling. High-density mapping performed using a multi-electrode array. In patients, distance from...
Cast bracing (CB) has been a well established method of treating tibial shaft fractures. Majority the recent literature on treatment fractures have upheld intramedullary nailing (IMN) as choice. Most these studies are from west, in public funded health set ups and hospitals with very low rates infection. This lead to bewilderment minds surgeons wishing opt for conservative countries scarcity resources. We therefore undertook this study compare two modalities scenario developing world....
Atrial fibrillation (AF) following coronary artery bypass graft surgery (CABG) is common and results in significant increases hospital stay financial encumbrance.Determine use the predictors of postoperative AF (POAF) CABG to develop a new predictive screening tool.A retrospective case-control study evaluated 388 patients (98 developed POAF 290 remained sinus rhythm) who undertook at Townsville University Hospital between 2016 2017. The demographic profile, risk factors for including...
Forty-eight children with an average age of 7.2 years (range: 3-12 years) were examined clinically and radiographically at 4-year follow-up 2-10 years), between 1989 2000 to analyze correction deformities following tibial shaft fractures. An inconsistent alteration in the length fractured tibia was observed. Anterior angular deformity realigned maximally (52.7%) followed by varus (40.9%) valgus (23.9%) deformities. Posterior corrected least (18.5%). In sagittal plane, acceptable critical...
There is increasing evidence of the role direction-dependent conduction plays in arrhythmogenic interaction between ectopic triggers and abnormal atrial substrates. We thus sought to characterize chronically stretched atria. Twenty-four patients with chronic stretch due mitral stenosis 24 reference left-sided accessory pathways were studied. Multipolar catheters placed at lateral right atrium, crista terminalis, coronary sinus (CS) characterized along linear across terminalis. Bi-atrial...
Free fat graft interposition has been used extensively in management of physeal injuries with established growth disturbances. The use this technique as part the acute not reported. Here we report on its application injuries, where it prevented formation an anticipated arrest.
Nineteen acute fractures and fourteen fracture complications of the femoral shaft were managed with ASIF plate fixation. Two patients having shortening procedures similarly managed. Most injuries involved distal shaft, judged unacceptable for intramedullary nailing. Single fixation immediate mobilization knee joint possible in most patients. Technical failure, refracture through an end-screw hole, or nonunion occurred 20% injuries. Plate is not surgical procedure choice management It...
Right ventricular (RV) pacing can lead to progressive dysfunction over a certain period. This pacemaker-induced cardiomyopathy (PiCMP) may be more common than previously reported. Speckle tracking imaging is recent development in echocardiography that identify left (LV) even before the LV ejection fraction (LVEF) value decreases. Three-dimensional (3D) has made accurate assessment of LVEF possible. The objectives this study are incidence RV PiCMP using 3D and strain analysis follow-up 6...
